Physically constrained routing in 10-gb/s DWDM networks including fiber nonlinearities and polarization effects

Dynamic optical communication systems require fast assessment of the signal quality of the desired path through the network. This paper presents an analytical approach for describing the Q-factor due to linear (group velocity dispersion, noise, and polarization-mode dispersion) as well as the dominant nonlinear effects in 10-Gb/s nonreturn-to-zero ON-OFF keying transmission systems.
